This Mitsubishi Electric Multi Split Set combines three MSZ-HR series indoor units, each with 2.5 kW, with an MXZ-3HA50VF2 outdoor unit with 5.0 kW cooling and 6.0 kW heating capacity. The Wi-Fi interface is built into each indoor unit; no additional module for app control is required. The energy efficiency classes are A++ for cooling and A+ for heating on the A+++ to D scale, with a SEER of 7.3. As a guideline, each indoor unit is suitable for rooms measuring approximately 19 to 25 m²^*.

Performance and range of use

The Mitsubishi Electric MXZ-3HA50VF2 outdoor unit has a specified cooling capacity of 5.0 kW and heating capacity of 6.0 kW, while each of the three MSZ-HR25VFK indoor units has a cooling capacity of 2.5 kW and heating capacity of 3.15 kW. Together, this results in 7.5 kW at the indoor units, which is 2.5 kW more than the outdoor unit. The operating range of the outdoor unit is specified as minus 15 to plus 46 °C. For the pipe connections, all three indoor units specify 6.35 mm on the liquid side and 9.52 mm on the gas side.

The stated area of approximately 19 to 25 m²^* applies per indoor unit and is a guideline based on standard room height and normal insulation standards, not a binding design. Room height, insulation standards, window areas, shading, and the number of people and devices are decisive. In addition, with this set, the three indoor units share an outdoor capacity that is significantly below their combined total; find out more about this in the frequently asked questions. We can check the appropriate design for your property upon request.

* Guideline based on the cooling capacity specified by the manufacturer, at a standard room height of approximately 2.5 m, normal insulation standards, and average sunlight exposure. Different conditions on site, such as large window areas, sloped roofs, or a high number of people, may require a different performance class. The binding design is carried out on a property-specific basis. For a professional design of your property, please contact us.

Detailed functions

Built-in Wi-Fi

Yes, and without an additional module. According to the manufacturer, the Wi-Fi interface is built into the indoor units of the MSZ-HR series. You connect each indoor unit to your home network and operate it via the manufacturer's app; this page does not state the exact name of the app, but we will provide it to you upon request. The delivery also includes three remote controls, one for each indoor unit.

Multi Split principle

Three indoor units are connected to a single outdoor unit. Each has its own refrigerant circuit, its own remote control, and its own setpoint temperature. Outside stands one unit, with a designated space and an electrical supply line for three rooms.

For installation, three pipe runs must be routed, and they are identical because all three indoor units have the same connection dimensions.

Operating modes

• Cooling and heating via the same unit
• Operating range of the outdoor unit from minus 15 to plus 46 °C
• Three separate refrigerant circuits, one per indoor unit
• Individual control per room via the respective remote control or the app

Control and comfort

• Three remote controls included, one for each indoor unit
• Wi-Fi interface in every indoor unit, operation via app

Frequently asked questions

What cooling and heating capacity does the set have?

The MXZ-3HA50VF2 outdoor unit has a specified cooling capacity of 5.0 kW and heating capacity of 6.0 kW, while each of the three indoor units has a cooling capacity of 2.5 kW and heating capacity of 3.15 kW. The energy efficiency classes are A++ for cooling and A+ for heating on the A+++ to D scale, with a SEER of 7.3 and a SCOP of 4.0.

Can I control the system via an app?

Yes, and without an additional module. According to the manufacturer, the Wi-Fi interface is built into the indoor units of the MSZ-HR series. You connect each indoor unit to your home network and operate it via the manufacturer's app; this page does not state the exact name of the app, but we will provide it to you upon request. The delivery also includes three remote controls, one for each indoor unit.

How do three indoor units work with one outdoor unit?

Via three separate refrigerant circuits, one per indoor unit. Each room is controlled individually, while the power is provided by a single outdoor unit.

What happens if all three indoor units run at the same time?

You should know this about this set in advance: together the three indoor units require 7.5 kW, while the outdoor unit is specified at 5.0 kW. This means 2.5 kW is missing if all three rooms are at full load at the same time, which is half the power of the outdoor unit. The set is designed for rooms that are used at different times: if one indoor unit runs alone, it has the full power available; if two run, both achieve their 2.5 kW. If all three rooms are to run at full power simultaneously for extended periods, we recommend a more powerful outdoor unit and can calculate this for you upon request.

What rooms is this set suitable for?

According to the manufacturer's specifications, each indoor unit covers approximately 19 to 25 m²^*. With three identical indoor units, the set is suitable for three smaller to medium-sized rooms, such as three bedrooms or children's rooms, or a living room plus two bedrooms in an apartment. At 21 dB(A) on the lowest setting, bedrooms are possible. We carry out the binding design on a property-specific basis.

How many indoor units are included in the delivery?

Three, all with 2.5 kW, plus three remote controls and one Mitsubishi Electric MXZ-3HA50VF2 outdoor unit. Pipes, installation material, and the bracket or console for the outdoor unit are not part of the delivery.

Is an installation set required for each indoor unit?

Yes, three pieces, and all three are identical. The manufacturer specifies the connections as three times 6.35 mm on the liquid side and three times 9.52 mm on the gas side, for the indoor units as well as the outdoor unit. You therefore need three times the same pipe set. Installation material is not included in this offer and is selected by the specialist company for the installation situation.

How large and how heavy are the units?

Each indoor unit measures 838 x 280 x 228 mm and weighs 8.5 kg. The outdoor unit measures 840 x 710 x 330 mm and weighs 57 kg. At this weight, a floor console is generally the simpler solution than a wall bracket; the specialist company assesses the load-bearing capacity on site.

How loud is the system?

For the indoor units, this page states 21 dB(A) on the low setting and 37 dB(A) on the high setting; we will provide you with the values for the intermediate settings upon request. For the outdoor unit, 46 to 50 dB(A) are specified, depending on the operating point. This page does not state a sound power level.

How far apart can the indoor and outdoor units be located?

This page does not state the permissible pipe length and the permissible height difference between the outdoor and indoor units. We will provide you with both values upon request. With three indoor units, the location of the outdoor unit determines the length of all three pipe runs.

Can I use the system for heating in winter?

For the outdoor unit, an operating range of minus 15 to plus 46 °C is specified; this page does not state separate limits for heating and cooling operation, but we will provide them to you upon request. In heating operation, the energy efficiency class A+ on the A+++ to D scale is specified, with a SCOP of 4.0. The heating capacity is higher than the cooling capacity, with 6.0 kW at the outdoor unit and 3.15 kW per indoor unit. Whether the system is sufficient as the sole heating for your rooms, we can check upon request.

Can I install the air conditioner myself?

Installation and commissioning of a Multi Split air conditioner is carried out by a certified specialist company; self-installation is not intended. The outdoor unit weighs 57 kg; the specialist company assesses the installation space and load-bearing capacity on site.
